VUE Audiotechnik hs-221 Dual 21-inch, ACM™ Powered Subwoofer System

VUE Audiotechnik hs-221 Dual 21-inch, ACM™ Powered Subwoofer System

The VUE Audiotechnik hs-221 is designed utilizing VUE’s revolutionary Active Compliance Management (ACM) technology for resetting the size-to-performance benchmark for subwoofer systems. The combination of ACM technology and the VUE Audiotechnik hs-221’s highly-sophisticated on-board electronics are resulting in a massive amounts of pure, clean low-frequency energy from a dual 21-inch configuration that embodies a significantly smaller enclosure than other dual 21-inch designs.

VUE’s patent-pending ACM technology is combining both band-pass and vented alignments into a single enclosure. The VUE Audiotechnik hs-221 is placing a two high performance, 21-inch transducers into this configuration, that comes with both woofers that share a common vented chamber. One woofer’s frontal radiation is direct, the second woofer’s frontal radiation is driving the band-pass chamber at the same time.

for making the two ACM subsections to combine acoustically the industry use sophisticated DSP to align the phase arrivals of the front facing woofer precisely, the common chamber vent, and output of the band-pass chamber vent. The powerful amplifier is sending a 1,000W of pure sine wave power (5,000W “burst”) with a unique optimal signal to each woofer. The combination of 5,000 watts of burst power is producing a 143 dB SPL peak output in free field (149 dB SPL half space – ground plane environment).

The combination of ACM, precision-engineered transducers, and sophisticated electronics, allow the VUE Audiotechnik hs-221 for delivering a very high output, and providing flat response down to 27 Hz (in ELF mode) at the same time. The hs-221’s enclosure has a more compact footprint than most dual 21-inch systems and even some dual 18- inch designs.

Features

• ACM™ Active Compliance Management: Patent-pending hybrid design combines both band-pass and vented alignments into a single, compact footprint for more output and definition
• Infrasonic Bass: Utilizing the ELF(Extended Low Frequency)  mode the hs-221 provides flat response down to 27 Hz and useable output to below 20 Hz without sacrificing transient or musical definition
• Tons of horsepower: Dual monaural amplifier modules supply 1000W pure sine wave power (2500W peak power) to each woofer
• Purpose-designed transducers: Dual 21-inch, long excursion with 5-inch (125mm) voice coils
• SystemVUE software: Mac, Windows, and iOS compatible software provides access to monitoring and control functions such as fully parametric EQ, speaker protection, input/output levels, volume, mute, delay and input sources
• Simplifies Setup of Directional Arrays: Software control and on-board DSP support virtually all directional array configurations without the need for external processing (factory presets included for basic CSA arrays)
• Standard IP for easy networking onboard: Simply plug-in, and the system automatically connects to virtually any kind of IP configuration
• Built for the road: Premium birch plywood enclosure with extensive internal bracing and a highly durable Dura Coat finish
